Application filed June 19,

To a l! whom it may concern:

Be it known that I, FERDINAND lV. Knoeii, oi San Francisco, State ofCalifornia, have invented certain new and useful Improvements inCentrifugal Conveyors, whereof the following is a specification.

This invention relates to centrifugal con-- veyers, and is intended moreparticularly for mining purposes, but is capable of other uses.

In its general features the invention coniprises a conduit through whichthe tailings, or other material to be conveyed, is conducted to arotating vessel, where a movementoti rotation is imparted to it, whichforces it into the mouth of a conductor and through the same to apoint0t delivery.

In the accompanying sheet of drawing I have illustrated the invention asused for mining purposes.

The figure isa sectional elevation of the entire apparatus.

In the drawings :a frame is represented by 1. This frame supports threecross brackets 2, 2) and 4, which in turn, support bearings for a shaftdriven by a pulley 6. Attached to the shaft so as to rotate with it is avessel This vessel is provided with a cover 8, and has interior vanes 9.which ensure the material. in it rotating with it. The material to bepumped is fed into a tank not shown and passes thence through theconduitll, and the channel 1'2, to the interior of vessel 7. in thevessel, the material receiving; centrifugal motion from the motion ofthe versell. is thrown into the open mouth 13 of the tube 1 1, andthrough the latter, and the channel 18 and tube 16, to a discharge tankor receptacle notshown.

The interior oi? vessel '7. as also of the various conduits may be linedwith asphaltuin or other means to protect them from acidity of thecontents.

in some cases a stutling box may be provided upon cover 8 to make atight joint between said cover and the conduit block as seen at 18 inthe figure, also the two chan- The shaft be 1 rotating; vessel. aconduit for feedingma- 1918. Serial no. 240,874.

nels 12 and 15 may be concentric, one with in the other, as also seen inthe figure. 19 is a chamber, having a cover 20, enclosing the stullingbox 18. The case when the feed and discharge channels are concentric isbest adapted for use when the vessel 7 isat the top of the shaft, asshown. In this case the inner channel 15 is supported in centralposition within the outer channel 12 by means of a collar 21., securedto the outer channel at the top end thereof.

Having thus described my invention, and an embodiment of it, in thefull, clear and exact terms required by law, and knowing that itcomprises novel, useful and valuable improvements in the art to. whichis per- .tains, I here state that I do not wish to be limited to the,prec1se construction and ar rangement of the several parts, as hereinset forth, as the same may be variously modified by a skilled mechanicWithout departing from the spirit of the invention.

lVhat I claim and desire to secure by Letters Patent of the UnitedStates, is the following, to-wit 1. Ar centrifugal conveyer comprising aterial into said vessel, means to discharge said material from saidvessel, a stui'iing box engaging said conduit for said vessel adapted toform an air tight connection therebetween and a closed chamber for saidstuil ing box.

2. A centrifugal conveyer rotating vessel, a conduit for feeding material thereto, and a conduit for discharging said materialthereifrom,oneoi said conduits being within the other, a cover for comprising a.

said vessel and a stuiling box upon said cover engagingsaid feedingconduiti in testimony, that I claim the iEOTJGgOlDg! l have hereto setmy hand this 11 day of June, 1918, in the presence of two witnesses.
